Vedclass · Answer

(C) Nitrogen $(N_2)$ and oxygen $(O_2)$ are the primary components of the atmosphere.They do not react under normal atmospheric conditions to form nitrogen oxides $(NO_x)$ because the reaction is highly endothermic and requires a very high temperature (e.g.,lightning or internal combustion engines) to overcome the high bond dissociation energy of the $N \equiv N$ triple bond.Therefore,both the assertion and the reason are correct,and the reason provides the correct explanation for the assertion.

$Assertion :$ Nitrogen and oxygen are the main components in the atmosphere but these do not react to form oxides of nitrogen.
$Reason :$ The reaction between nitrogen and oxygen requires high temperature.
